LIQUID-LEVEL INDICATOR.

Application filed October 15, 1921. Serial No. 507,845.

To all whom it may concern:

Be it known that I, CALvIN W. WILSON, a citizen of the United States,residing in the city of Winchester, in the county of Bandolph, State ofIndiana, have invented a new and useful Liquid-Level Indicator, of whichthe following is a full, clear, and comprehensive specification andexposition, the same being such as will enable others to make and usethe same with exactitude.

:The object of my present invention, broadly'stated, is. to provide agasoline gage which will'be strong and durable in con struction, easilyoperated and controlled, efficient and practical in operation, and whichcan be manufactured and sold at a comparative low price. a

More specifically stated,iny object is to provide a gasoline gageespecially intended for use when filling large tanks, such as tankwagons or tank trucks in which gasoline is transported from place toplace, the device being self-contained, and to be connected in operativeposition only when a tank is being filled.

Other minor objects and particular advantages of the invention willsuggest themselves in the course of the following specification and asset forth in the appended claims.

lhe preferred means for carrying out my invention in a practical manneris shown in the accompanying drawings, in which Figure l is a sideelevation of my device complete and in operativeposition in connectionwith a tank which is shown in cross section. Figure 2 is a centralverticalsection of my construction. Figure 3 is a top plan view of thesame. And Figure 4 is a front elevation thereof.

Similar indices denote like parts throughout the several views.

In order that the construction, the operation, and the advantages of myinvention may be more fully understood and appreciated, I will now takeup a detailed description thereof in which I will set forth the same asfully and as comprehensively as I may.

Referring now to the drawings in detail: Letter A denotes a tank incross-section, however, in order to economize space on the drawings thetank is shown much smaller with relation to the invention than it willbe in actual practice.

Letter B denotes a filling aperture, which is surrounded by the collar Cwhereby the aperture B may be closed, when desired, by means of a cap orplug, not shown.

The invention proper comprises a sheetmetal tubular body 1, the samebeing open at both ends to allow unobstructed passage therethrough, forthe purposes hereinafter set forth.

gAdjustably secured to the exterior of the bodyl is the support 2, thesame being secured parallel with the body by means of the bolts 3, thelatter being located in slots formed through the body 1, as is shown inFig. 2, in order to make it adjustable.

The support 2 projects above the upper end of the body 1, and extendingdirectly back horizontally from the upper end thereof, and formedintegral therewith, is the main-arm 4.

Numeral 5 denotes the sector, which is in the nature of a half-circlebar. The rear or outer end portion of the arm 4. is secured to thecenter of the sector 5 by means of the screw 6, which screw may belocked by means of the lock-nut'7.

Numerals 8 and 9 denote the other adjusting screws, they being threadedvertically through the end portions of the sector 5, and each is adaptedto be locked by means of the respective lock-nuts 10 and 11.

Numeral '12 denotes the measuring arm which has a foot 13 formedintegral therewith and at right angles thereto and eX- tending back fromits lower end and resting on the main-arm 4.- where it is secured by thebolts 14. The measuring-arm 12 extends directly upward, but it islocated slightly further rearward than is the support 2, as shown inFigs. 1 and 2.

Contacting with the underside of the arm 1 and secured thereto by thesaid bolts 14: is the angular guard 15 whose front portion extendsdownward in alinement with the arm 12, as shown.

Numeral 16 denotes a float which is located inside the body 1 beingconcentric with and slidable on the guide-rod 17.

The ends of said rods 17 extend out at right-angles and they are securedto the body 1, as by the nuts 18, whereby the rod 17 is retained insuspension in the center of the body 1 as shown.

At thelower portion of the rod 17 there is a cushion 19 on which thefloat 16 may rest, as shown in Fig. 2.

Secured to one side of the float 16 is the arm 20 to which is securedthe lower end of the indicator wire 21 which extends upward between thedownwardly extending portion of the guard 15 and the support 2, throughan aperture 22 in the arm 4 to the movable indicator 23 to which itsupper end is attached.

A retaining wire 2% extends from the ends of the indicator around thearm 12, but slidable thereon, whereby the indicator may slide up anddown on the arm 12 as the float raises and lowers.

The face of the arm 12 is graduated, as indicated by the marks 25 todenote gallons or other amounts, each indicated by a number arrangedprogressively from the lower end upward as shown.

The aperture 26 provides means whereby the device may be suspended whenit is not in use.

Operation: In filling the tank A the nozzle of the filling hose isinserted through the aperture B and then the attendant operates a pumplocated at a little distance from the tank, but it is usually in suchposition that it is impossible for the operator to determine the depthofthe. gasoline in the tank without discontinuing the pumping and thenlooking into the tank, but with this invention the operator may know atall tmes even at a distance, the precise height of the gasoline in thetank.

To use the device the cap is first removed from the tank, after whichthe device is inserted, bringing the vertical portion of the guard 15into contact with the collar C, after which the screws 6, 8 and 9 shouldbe adjusted up or down in order to level the sector 5, and thereforeplace the body 1 in vertical position.

It is nowevident that when the tank. is being filled that the float 16will be lifted from its seat and moved gradually upward, thereby causingthe indicator 23 to denote the amount of fluid in the tank at any time.After the tank has been filled then the device may be removed and theopening in the tank can then be closed, and the device may be preservedfor future use.

I desire that it be understood that various changes may be made in theseveral details of construction and operation without departing from thespirit of the invention and without sacrificing any of the advantagesthereof which are new and useful.

Having now fullyv shown and described my invention, what I claim anddesire to secure by Letters Patent of the. United States, is

1. A. liquid level indicator comprising a tubular body, asupporting-bar. adjustably attached to said body and extending there:above, a main. arm extending back from the upper end of the support, asector attached. to said arm, leveling screws carried byv the sector, ameasuring arm extending up from said main arm, a float located insidethe tub.- ular body, a guide rod on which said float is mounted, anindicator slidable on the face of the measuring arm, and a wireconnecting the indicator with the float, substantiallyv as.

shown.

2. A liquid level indicator comprising a tubular body having anunobstructed passage-way therethrough, a support adjustably secured tothe exterior of the body and parallel therewith and extendingthereabove, a main arm extending back from the upper end of the support,a sector carried, by said arm, a. measuring-arm extending upwardslightly rearward of said support and parallel therewith, means, forguiding said measuring-arm, a float located inside the body, a guide rodon which the float is slidable, an indicator slidable on the face of themeasuring arm, and means for Connecting the indicator with the float,all substantially as shown and described.

In testimony whereof I have hereunto subscribed my name to thisspecification in the presence of two subscribing witnesses.
